A design method for an ultra-wideband bandpass filter (BPF) with four coupled lines has been developed. For demonstration purposes, 50Ω-matched self-complementary antennas integrated with the ultra-wideband, differential-mode BPF with four coupled lines, a notch filter, and a low-pass filter (LPF) were prepared and tested. An optimized structure for a single-stage, broadside-coupled and edge-co...
To enhance the performance, various methods have been applied to design the antenna. Still the scope remains unchanged in antenna research. Antenna has a prime role in wireless communication. In recent years, researchers have focused on improvement of the UWB antennas. UWB has attractive merits compact size, low cost, resistant to severe multipath and jamming, ease of fabrication, and good omni...
A notch filter for the rejection of stray light from gigahertz range heating sources was developed to protect a vulnerable microwave plasma diagnostic system. As one of the applications, we consider the installation of the notch filter into the receiver of a collective Thomson scattering diagnostic in the Large Helical Device. Experimental observations indicate that two types of notch filters a...
Using composite right-left handed (CRLH) transmission line concept, a novel miniaturized dual notch band filter (DNBF) is proposed. The suggested DNBF consists of an interdigital transmission line (ITL), split ring resonators (SRRs) and complementary split ring resonators (CSRRs). Since the resonance frequency of the SRRs and CSRRs are quite independent of each other, the dual notch bands of th...
Two cooling methods are installed in the cooler synchrotron COSY. The electron cooler is used for stacking and cooling of proton beams with energies between 45 MeV and 180 MeV. After last year’s commissioning the stochastic cooling system became a standard tool for beam cooling in the momentum range of 1.5-3.3 GeV/c. The stochastic cooling pickups also serve for precision measurements of the ch...
This paper presents The Electromagnetic Interference effect from power line noise in Multi Speciality Hospital to Bio-Medical signals. The study includes the design of Bio-Medical signal Generating circuits that is used to eliminate the power line noise from the signal. The Bio-Medical system basically is a combination of Instrumentation Amplifier, High pass filter, Low pass filter, and Notch f...
Power decoupling of pulsating grid side power from constant source side power is one of the paramount issues in single phase-phase grid-connected renewable systems. The principal aim of such systems is the decrease of the capacitance of the decoupled capacitor. However, this causes some problems such as an increase in the total harmonic distortion (THD) of injected current to the grid and bus v...
A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...
